Resumen
Un estudio realizado en el 2007 por los investigadores Gaby Dolz y Juan José Romero, del
Programa de Medicina Poblacional de la Escuela
de Medicina Veterinaria de la Universidad Nacional (EMV-UNA), evidenció una alta prevalencia de la paratuberculosis o Enfermedad de Johne
en bovinos de leche de Costa Rica, por lo que se
hace necesario implementar la vigilancia epidemiológica de este agente en los hatos lecheros.
La paratuberculosis es una enfermedad incurable
de los rumiantes, causada por la Mycobacterium avium
subespecie paratuberculosis (MAP). Esta bacteria ocasiona una enteritis granulomatosa, que se manifiesta
con diarreas persistentes o recurrentes, que no responden a tratamientos con antibióticos. Está mundialmente
distribuida y afecta al ganado bovino, ovino y caprino.
También se han identificado especies animales en estado
salvaje como venados, conejos y zorros, que sirven como
reservorios de la enfermedad.

Paratuberculosis is an incurable disease of ruminants caused by Mycobacterium avium subspecies paratuberculosis (MAP). This bacterium causes a granulomatous enteritis, which manifests with persistent or recurrent diarrhea that does not respond to antibiotic treatment. It is distributed worldwide and affects cattle, sheep and goats. Wild animal species such as deer, rabbits and foxes have also been identified as reservoirs of the disease.
